INTRODUCTION

Green computing or green IT, refers to environmentally sustainable computing or IT.

It is "the study and practice of Designing, Manufacturing, Using, and Disposing of computers, servers, and associated subsystems efficiently and effectively with minimal or no impact on the environment.

It is an environmental friendly IT where the main objective is to reduce the hazardous materials and maximize the energy efficiency .

Why is Green Computing required?

•Computer consumes a lot of energy.

•Printing often unnecessary stuff is waste

•Reduce pollution.

•Reduce the power consumption

•reduce the global warming

•Toxicity.

.

•It originated in 1992 at the U.S Environmental Protection

Agency that launched Energy Star program.

•Shortly after that the term “Green Computing” was

coined.

•Shortly after that the Swedish also launched the TCO

Certification.

 

HISTORY 

Green Use

Green Disposal

Green Design

Green Manufacturing

Road to Green Computing

CPU uses 120 Watts

CRT uses 150 Watts

Energy use comes from

o electrical current to run the CPU, motherboard,

memory

orunning the fan and spinning the disk(s)

omonitor (CRTs consume more power than any

other computer component)

oprinters

Energy Consumption

•Product Longevity

•Software & deployment optimization

•Power management

• Materials Recycling

•Virtualization

•Algorithm Efficiency

• Power Supply

•Display

•Storage

• Telecommunicating

APPROACHES 

Carbon Free Computing Solar Computing RoHS Computing Virtualization

Methods to implement Green Computing

•Turn off the computer when not in use, even if just

for an hour

•Turn off the monitor when not in use (as opposed

to running a screen saver)

•Use power saver mode 

•Use LCDs instead of CRTs as they are more

power efficient

•Use hardware/software with the Energy Star label

•Choose Intel & VIA Processors in comparison to

AMD Processors.

•Sustainable Green Computing Plan

•Reduce Paper Consumption

•Conserve Energy

•Recycling

Steps For Green Computing

 Energy saving

Environmentally Friendly

Cost-effective ( pays over time )

Save more money per year

Can give you a tax right off

ADVANTAGES

High start up cost

Not readily available

Still in experimental stages

Sacrifice performance for battery life

Not for everyone

DISADVANTAGES

The plan towards green IT should include new

electronic products and services with optimum

efficiency and all possible options towards

energy savings. That is enterprise wise

companies are laying emphasis on moving

towards Eco Friendly Components in Computers,

the use of eco-friendly sustainable components

will become the norm rather than the exception in

future.

Future of Green Computing

The greenest computer will not miraculously fall

from the sky one day, it’ll be the product of years

of improvements. The features of a green

computer of tomorrow would be like: efficiency,

manufacturing & materials, recyclability, service

model, self-powering, and other trends.
